	intracellular,cytoplasm,cytosolic

basic FUNCTION	playing an important role as an IL22 antagonist in the regulation of inflammatory response
	plays a crucial role in controlling tumorigenesis and epithelial cell proliferation in the colon
	IL22 and IL22RA2 are regulated during intestinal tissue damage
	promotes bacterial uptake into Peyer patches (PPs) by influencing follicle-associated epithelium (FAE) gene expression and function

INTERACTION

DNA

RNA

small molecule

protein	IL22 (blocking its interaction with cell surface IL22R complex)
	regulation of IL22RA2 is crucial to control the effects of IL22 during intestinal tissue damage and tumorigenesis
	IL22RA2 is a soluble IL22 receptor, which antagonizes IL22 activity and has genetic associations with autoimmune diseases

REGULATION

Other

regulation of IL22RA2 via the inflammasome provides an unanticipated mechanism, controlling IL22 and thereby the development of colon cancer
